Abstract
The present disclosure is an optical measurement system for measuring Rayleigh scattered light and Brillouin scattered light in an optical fiber by injecting light into both ends of the optical fiber, wherein injected light for the Rayleigh scattering includes frequency multiplexing pulses, and one pulse of the frequency multiplexing pulses is used as pump light for the Brillouin scattering.
